To all whom it may concern:

Be it known that I, JOHN L. GIDEoN, a citizen of the United States, anda resident of Omaha, in the county of Douglas and State of Nebraska,have invented certain new and useful Improvements in Paper- FeedingAttachments for Gordon Presses, of which the following is aspecification.

My invention relates to printing presses and more particularly topresses of the Gordon type.

It is the object of my invention to provide mechanism which may bequickly and easily attached to or removed from a press of the describedclass, and which will enable paper from a roll to be automatically fedto printing position upon the platen, cut into sheets after the printingthereof, and the severed sheets stacked in a pile, so that the operationof the press is made automatic, and hand-feeding dispensed with.

In the accompanying drawings Figure 1 is a side view of a press equippedwith mechanism embodying my invention, Fig. 2 is a detail side view ofthe mechanism, Fig. 3 is a plan view thereof, Fig. 4 is a View similarto. Fig. 2 but showing the parts at different positions, Fig. 5 is adetail longitudinal vertical section through the feed and cut-offmechanism on the plane of the line ma2 of Fig. 3, and Fig. 6 is a detailhorizontal section of the feed-roll driving device.

In carrying out my invention I employ an ordinary oscillatingbed-and-platen printing press of the Gordon type, such as is commonlyused for job printing. Such a press is prepared for the attachment of myroll-feeding mechanism by removing the feed-table employed when thepress is used for printing hand-fed sheets, disconnecting the actuatingdevices for the rocker which carries the platen, and disconnecting thedevices for releasing-the rocker-lock which holds the rocker at theimpression position.

As the means for actuating the rocker and releasing the rocker-lock arecams which engage rollers connected with the respective parts, the mereremoval of the cam-rollers serves to effect the desired disconnection ofthe said parts from the actuating mechanism. The rocker and platen areplaced and locked at the compression position, as shown in Fig. 1. v y

In the press shown in Fig. 1, the principal parts, and those common toall presses of this class, are as follows: The side-frames 1, the bed 2which is pivoted to the lower rearward portions of the side-frames, therollerframes 3, ink-rollers 4, inkdisk 5, side-arms 6 for actuating thebed, the main or driving shaft 7, the front-shaft 8, the large gear andcam wheel 9 which is secured on one end of the front shaft and is drivenby a pinion 10 carried on the main shaft 7, the small cam-wheel 11carried on the end of the front-shaft opposite the wheel 9, therocker-shaft 12, the rocker 13, the platen 14, and the roller-arms 15.

It will be understood that all of the parts mentioned are of ordinaryconstruction and operation, the roller-arms 15 connecting theroller-frames with the side-frames, and the side-arms 6 connecting thebed with the wheels .9 and 11, said wheels having crankpins on the outersides thereof for this purpose. The cams, before mentioned, whichordinarily actuate the rocker and release the rocker-lock, are on theinner sides of the wheels 9 and 11 and are not shown in the drawing.

On the upper edges of the side-frames 1 are secured the side-pieces 16and 17 of the paper-feeding and cut-off mechanism, which has the sameposition on the pressframe as the table which is used for ordinaryhand-feeding of the press. A roller 18 is journaled in the side-pieces16 and 17 and above said roller is a skeleton roller comprising a shaft19 and disks 20 secured at intervals thereon. The ends of the shaft 19extend into vertical slots in the sidepieces, and half-boxes 21 arearranged in the slots above the shaft, adjusting-screws 22 beingprovided by which the shaft may be pressed down to force the disks 20toward the feed-roller 18. On the end of the feed-roller shaft outsidethe side-piece 16 is secured a ratchet-wheel 23. Between theratchet-wheel and the side-piece an arm 24 and a pinion 25 are revolublymounted on the shaft, the arm and pinion being secured together, and thearm carrying a pawl 26 for engaging the ratchet-wheel. A rack 27 isslidably held in a suitable longitudinal guideway in the side-piece 16and meshes with the pinion 25. The rack is given a longitudinalreciprocating movement, so as to revolve the pinion and pawlarmalternate directions, the movements a communicated to the ratchet-wheeland feed-roller, so that. the latter is rotated intermittently inamounts proportionate to the length of the stroke of the rack 27.

Adjustable actuating means for the rack are provided, so that themovements of the feedroller may be proportioned to the width of thesheets to be printed and cut off from the strip of paper fed to thepress. In the structure shown, therack-actuating means include an arm orlever 28 of which the' lowerend is;pivoted onthe main-shaft 7 and theupper end is connected by a rod 29 with the front end of the rack. Thelever 28 extends ,up outsidethe sidearm .Gwhich is connected with thecrank-pin 30 on the large gearwheel 9. The centraLportion of the leveris. slotted longitudinally, and astud 31 passesthrough the slot and isprovided with a collarand a nut 32which may be tightened down to holdthe stud at adjusted positions with respect to j the lever. On the outerend ofthe crank-pin 30 is'secured a bar 33 which extends from the pintoward the axis ofthe shaft 8, but not radialthercto. Onthe outer sideof the bar are two lugs in which is revolubly mounted a rod 34 .of whichthe central portion is threaded and passes through a stud 35. The innerend. of thestud extends into a slot in the bar, behindand parallel tothe rod 341. By turning therod 3athe position of the stud may be variedlongitudinally of the bar. The inclination of: the barto a line radialto the axis of the shaft 8 is such that as the position of the stud isvaried longitudinally of the bar it will beat agreater or lessdistancefrom the axis of the shaft but will alwaysbe slightly in advanceof the crankpin' 30,]with reference to the direction of rotation ofv theshaft and the wheel 9 as indicated in Figs. 2 ands. A bar 36 has itsendspivotally connectedwith the studs 31 and 35, forming aconnecting-rod by which the rotation of the wheel 9 .will cause anoscillating movement of the lever 28 between two extreme positions suchas those shown in Figs, 2. and 4:. It will be obvious that the desiredvariation of the stroke ,of the rack 27 may be effected by varying therelations of, the stud to the bar 33 and of thestud 31 to the lever 28.

idrical and has an inlaid .strip 39 of hard material at oneedge,adaptedto cooperate withthe ledger-bar to cutoff ,sheets from the str p. ofpaper ,passing over the same.

The cutter-bar carriesat one-send, ,outside the side-piece 17, an arm 10from which a connecting-rod 41 extends to and is pivotally connectedwith the upper arm 42 of a threearmed leverwhichis pivoted on theprotruding end of the feed-roller shaft. The two lower arms 13 and 4A ofthe said lever carry rollers 45 and 46, respectively, disposed adjacentto the periphery of the wheel 11.. Onsaid wheel is secured a cam-lug 47adapted to engage the rollers 45 and 416 successively during therotation of the wheel in the direction indicated. As the cam-lug engagesthe roller 45 the three-armed lever is tiltedso that the arm &0 is movedforwardly and causes thecutter-bar to be rotated sov that its cuttingedge moves downward adjacent tothe -ledger-bar. The cam-lug then engagesthe roller9i6 and tilts the lever backwardly to restore the cutter-barto its normal position.

The sheets B as severed by the cutter-bar fall in a pile .ona receiving-table a s which is.re1novably supported in a-slightly inclinedposition, as shown,-by means of rods 4:9 which extendu-p from the tableand hook over-a: transverse rod 50. The rods as) serve as stops for thefront edges of the sheets B.

To the lower andrearward parts of the pressside-frames 1 are connectedthe ends of bars 51 .which extend rearwardly between thefoot-portionsofrthe bed 2 and have leg-portionswhichrest upon the floor or pressfoundation. Near the rearward ends of the bars 51 are bearings for ashaft 52 adapted; torevolublysupport a roll paper a. On the intermediateportions. the bars 51 are vertically extending pins 53 with which theends of atransverse bar 54 are slidably connected. The strip. of paperA,fro1n the roll a is passedfor-wardly beneath the bar 54, thencediagonally upward between the.footportions of the bed 2, and

The paper strip is thence carried upwardly 1 1 over the face oftheplaten 14- and-over a roller 57 which is ournaled in the rearwardportions of the side-pieces 16 and 17 From the roller 57 the. strip ispassed around the take-up rollers :58 and .59, and thence between thefeed-roller 18 and disks 20. The take-up rollers 58 and 59 are revolublymounted on arms 60secured on av transverse shaft 61 of which the endsare journaled in theside-pieces16 and 17. A notched wheel '62, issecured on theshaft 61, and two pawls v63 are mounted ontheside-piece 17so as to beengageablewithsaid wheel to hold. thesame and the shaft invarious adjusted positionswith respect-,to. the-frame. By so adjustingthe shaft the ,positions of the rollers 58 and 159 may be varied so thatvarious lengthsaof the paperstrip will be required to extend fromtheplaten to the cut-elf device, and, the printed port ions, of

the strip A thus brought into the proper relation to the cut-off,regardless of the width of the sheets cut from the strip.

In the operation of the press the typeform is secured upon the bed andinked in the usual manner, and all of the mechanism in connection withthe bed operates in the usual way. The platen remains stationary at theimpression position, as before described. During each movement of thebed toward the impression position the paper strip A is moved forward bythe action of the feeding mechanism, the forward movement ceasing justbefore the bed reaches the impression position, so that the impressionis made while the paper is drawn tight over the platen. The describedsequence in the termination of the feeding movement and the making ofthe impression is attained by the relations established between thecrankpin 30 and stud 35, before described, whereby the position of thestud which actuates the feed mechanism is always slightly in advance ofthe crank-pin which actuates the bed. During the time that the paperstrip is stationary, the portion thereof extending beyond the ledger-baris severed by the cutter-bar and falls onto the receivingtable 48. Atthe beginning of the feeding movement the transverse bar 54 slidesupwardly on the pins 53 and thus reduces the stress on the paper stripwhile the movement of the roll a is beingstarted. At the conclusion ofthe feeding movement the slack in the strip A, due to movement of theroll resulting from its inertia, is taken up by downward movement of thebar 54. The bar thus forms an automatic slack takeup for the paperstrip.

Now, having described my invention, what I claim and desire to secure byLetters Patent is:
